CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 330,968, dated November24, 1885.

Application filed September 15, 1885. Serial No. 177,217. (No model.)Patented in Canada July 31, 1885, No. 22,158.

To all whom it may concern.-

Be it known that I, Dosrrnnn DUPRAT, of Ste. Scholastique, in the countyof Two Mountains and Province of Quebec, Canada, have invented certainnew and useful Improvementsin Oar-Axle Lubricators; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

My invention has reference to that class of lubricators in which the oilis fed to the surface of the axle by a roller held in immediate contactand rotated'with it.

Up to the present time it has been necessary, in order to use thislubricating apparatus, to change the construction of the axlebox toallow of its introduction. To do away with this necessity, and toprovidea rollerlubricator which may easily and quickly be placed in position inany ordinary axle-box without altering it in any way, are the objects ofmy invention. It may be thus described: The lubricating-roller has itsbearings carried in boxes supported on springs contained in the hollowstandards formed on or secured to a bed-plate the full width of theaxle-box. This bed-plate I propose to make with a side flange hinged orpivoted to the main part, on which are the standards, so that thisflange can be turned up and thelubricator placed on one side of the box,so as not to interfere with the enlarged end of the axle when it isintroduced. \Vhen the axle is in place, the lubricator can be broughtunder it and the flange let down.

For full comprehension of the invention reference must be had to theannexed drawings, in which- Figure 1 is a longitudinal section throughthe axle-box, showing the lubricator in place; and Fig. 2, acrosssection through the axlebox, showing position of lubricator whenthe axle is introduced.

Similar letters of reference indicate like parts.

A is the axle, and B the axle-box, both of any usual construction, notneeding modification in any way. 0 is the lubricating-roller, preferablyof Wood, and any desired length and diameter, having its bearingsusually carried in hollow boxes 0, supported by springs d in thestandards D. E is the bed-plate carrying these standards, and being,when laid flat, approximately the full width of the axlebox. IE is theflange hinged to bed-plate E, the two parts having their meeting edgesinterprojecting, and with eyes formed on them, and a pivot-pin, e,passing through such eyes. F F are springs serving to hold the flange Ein either a vertical or horizontalposition.

Having thus described my invention, I beg to state that what I claim isas follows:

In a car-axle lubricator, the combination of the lubricating-roller,standards in which the same is carried, and bed-plate on which these aremounted, formed with a folding-up flange, as and for the purposes setforth.
